ABSTRACT
The present study investigated the effect of Euphorbiae Pekinensis Radix(EPR) on intestinal flora structure before and after vinegar processing and explored the detoxification mechanism of vinegar-processed EPR. In this study, the extraction efficiency of casbane diterpenes from EPR with different solvents was investigated, and the optimal solvent was selected to enrich these components. After 14 days of intragastric administration of total diterpene extract of EPR and vinegar-processed EPR, 16 S rDNA sequencing technology was used to detect the structural changes of intestinal flora. The flora related to the intestinal toxicity of EPR was screened out based on the results of intestinal pathological damage by correlation analysis. The results showed that Soxhlet extraction with chloroform as extraction solvent could enrich Casbane diterpenes in EPR. As revealed by 16 S rDNA sequencing results, EPR could significantly change the structure of intestinal flora, which could be reversed by vinegar-processing EPR. Some intestinal flora candidates might be related to detoxification of vinegar processing. The correlation analysis of intestinal flora candidates and indexes related to intestinal mucosal injury showed that compared with EPR, vinegar-processed EPR could down-regulate the abundance of some pathogenic bacteria such as Mucispirillum, Bilophila, and Ruminiclostridium, and up-regulated some probiotics such as Enterorhabdus, Ruminococcaceae_UCG-014, Barnesiella, and Candidatus. The intestinal toxicity caused by EPR may be related to the disturbance of intestinal flora, and vinegar-processed EPR can improve intestinal flora disorder by up-regulating the abundance of probiotics and down-regulating the abundance of pathogenic bacteria to remodel the intestinal mucosal barrier and reduce toxicity.
